什麼是base64呢？簡單來說，在MIME格式的email中，將binary轉成ASCII的一種方法，把原本的二進制取6個bit為一個單位，用大寫字母(26個)、小寫字母(26個)、0~9(10個)和加除號"+ /"(2個)，總共64個(26+26+10+2=64)，基於這64個字元的編碼方式，可以簡單地做文字的加密。
以下以sign.txt文字檔案為例子
Sign.txt
------------------檔案內容----------------------
Content-type: text/plain
Test OpenSSL Signed Content
------------------檔案內容----------------------
透過簽章之後得到的結果如下，SMIME格式，上半部包含了原本檔案的內容，下半部則是base64的編碼結果。

而最後一個DER格式，因為是使用二進制編碼，格式上主要為TLV(text, length, value)，也就是說每個字串會包含最前頭的代表、字串長度以及數值。有興趣可以參考http://en.wikipedia.org/wiki/Type-length-value
因此可以在裡面看到很多簽章的格式細節，使用16進制檢視結果如下所示：
